[PR][Feature] Add support for changing the tier of an adversary (#1503)
* Add support for changing the tier of an adversary * Move scaling data to actorConfig * Use a new algorithm using the median average deviation * Fine tune damage conversion for actions * Use standard deviation instead and change dialog type * Use daggerheart style for dialog * Formatting * Improve handling of minions and hordes * Changed to using lookup for Group Attack damage * Added lookup for Horde feature * Remove spaces in damage formulas --------- Co-authored-by: WBHarry <williambjrklund@gmail.com>
